Leptin plays an important role in appetite and energy regulation via signaling through melanocortin receptors (MCRs) in the brain. As serum levels of MCR ligands are elevated in a clinical situation [acute-phase response (APR)] to tissue damage, where the liver is responsible for the metabolic changes, we studied hepatic gene expression of MCRs in a model of muscle tissue damage induced by turpentine oil (TO) injection in rats. A significant increase in gene expression of all five MCRs (MC4R was the highest) in liver at the RNA and protein level was detected after TO injection. A similar pattern of increase was also found in the brain. Immunohistology showed MC4R in the cytoplasm, but also in the nucleus of parenchymal and non-parenchymal liver cells, whereas MC3R-positivity was mainly cytoplasmic. A time-dependent migration of MC4R protein from the cytoplasm into the nucleus was observed during APR, in parallel with an increase in alpha-MSH and leptin serum levels. An increase of MC4R was detected at the protein level in wild-type mice, while such an increase was not observed in IL-6ko mice during APR. Moreover, treatment of isolated liver cells with melanocortin agonists (alpha-MSH and THIQ) inhibited the endotoxin-induced upregulation of the acute-phase cytokine (IL-6, IL1 beta and TNF-alpha) gene expression in Kupffer cells and of chemokine gene expression in hepatocytes. MCRs are expressed not only in the brain, but also in liver cells and their gene expression in liver and brain tissue is upregulated during APR. Due to the presence of specific ligands in the serum, they may mediate metabolic changes and exert a protective effect on liver cells."],["dc.identifier.doi","10.1007/s00418-011-0899-7"],["dc.identifier.isi","000300326100002"],["dc.identifier.pmid","22183812"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7321"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/27120"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0948-6143"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Melanocortin receptors in rat liver cells: change of gene expression and intracellular localization during acute-phase response"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Medical history, best corrected visual acuity (BCVA), best corrected high/low contrast visual acuity (BChcVA/BClcVA), mean sensitivity (MS) and mean defect (MD) in central visual field testing, and FAZ size in fluorescein-angiography (FAG) were recorded.

Results: Thirty-six of 40 patients were included. MS differed significantly between G1 (n = 6) and G2 (n = 30), and BChcVA/BClcVA as well as TMV correlated significantly with FAZ size in correlation analysis. Mean HbA1c tended to be lower in G1 than G2. Patients in G1 were slightly older than in G2. Treatment period with insulin was shorter in G1/Q1 than in G2/Q3.

In severe ill patients, death does not occur due to failure of hemostasis, either medical or surgical, but mainly from comorbidities, treatment complications, and decreased tolerated blood loss. Management strategies have changed dramatically over the last two decades and include primarily endoscopic intervention in combination with acid-suppressive therapy and decrease in surgical intervention. Herein, we present one of the largest patient-based analysis assessing clinical parameters and outcome in patients undergoing endoscopy with an upper GI bleeding. Data were further analyzed to identify potential new risk factors and to investigate the role of surgery. In this retrospective study, we aimed to analyze outcome of patients with an UGIB and data were analyzed to identify potential new risk factors and the role of surgery. Data collection included demographic data, laboratory results, endoscopy reports, and details of management including blood administration, and surgery was carried out. Patient events were grouped and defined as \"overall\" events and \"operated,\" \"non-operated,\" and \"operated and death\" as well as \"non-operated and death\" where appropriate. Blatchford, clinical as well as complete Rockall-score analysis, risk stratification, and disease-related mortality rate were calculated for each group for comparison. Overall, 253 patients were eligible for analysis: endoscopy was carried out in 96% of all patients, 17% needed surgical intervention after endoscopic failure of bleeding control due to persistent bleeding, and the remaining 4% of patients were subjected directly to surgery. The median length of stay to discharge was 26 days. Overall mortality was 22%; out of them, almost 5% were operated and died. Anticoagulation was associated with a high in-hospital mortality risk (23%) and was increased once patients were taken to surgery (43%). Patients taking steroids presented with a risk of death of 26%, once taken to surgery the risk increased to 80%. Patients with liver cirrhosis had a risk of death of 42%; we observed a better outcome for these patients once taken to theater. Clinically, once scored with Blatchford score, statistical correlation was found for initial need for blood transfusion and surgical intervention. Clinical as well as complete Rockall score revealed a correlation between need for blood transfusion as well as surgical intervention in addition with a decreased outcome with increasing Rockall scores. Risk factor analysis including comorbidity, drug administration, and anticoagulation therapy introduced the combination of tumor and non-steroidal antirheumatic medication as independent risk factors for increased disease-related mortality. UGIB remains challenging and endoscopy is the first choice of intervention. Care must be taken once a patient is taking antirheumatic non-steroidal pain medication and suffers from cancer. In patients with presence of liver cirrhosis, an earlier surgical intervention may be considered, in particular for patients with recurrent bleeding. Embolization is not widely available and carries the risk of necrosis of the affected organ and should be restricted to a subgroup of patients not primarily eligible for surgery once endoscopy has failed. Taken together, an interdisciplinary approach including gastroenterologists as well as surgeons should be used once the patient is admitted to the hospital to define the best treatment option."],["dc.identifier.doi","10.1007/s00423-017-1552-2"],["dc.identifier.isi","000400365500012"],["dc.identifier.pmid","28091770"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42673"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Springer"],["dc.relation.issn","1435-2451"],["dc.relation.issn","1435-2443"],["dc.title","Relevance of surgery in patients with non-variceal upper gastrointestinal bleeding"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Detailed analyses however concerning the phenotype and maturation of DC as well as the mechanisms underlying their recruitment are still lacking for Crohn's disease. Methods: Different myeloid and plasmacytoid DC subsets were characterised by immunohistochemistry. Expression of the so-called \"lymphoid' chemokines CCL19, CCL20, and CCL21 was determined by real time reverse transcription-polymerase chain reaction in Crohn's disease and normal controls. Furthermore, expression of CCL19, CCL20, and CCL21 as well as their receptors CCR6 (for CCL20) and CCR7 (for CCL19 and CCL21) was characterised by immunohistochemistry and, in addition, their cellular localisation was determined by double immunofluorescence investigations. Results: Colonic tissue affected by Crohn's disease was characterised by an increased number of mature myeloid DC forming clusters with proliferating T cells. In keeping with their advanced maturation, DC possess the chemokine receptor CCR7. Increased expression of the CCR7 ligands CCL19 by DC themselves as well as CCL21 by reticular cells and lymphatic vessels was observed in Crohn's disease, thereby causing the matured DC to be trapped at the site of inflammation. Conclusion: Our results demonstrate that autocrine and paracrine actions of lymphoid chemokines in Crohn's disease may lead to increased numbers of mature DC away from their usual migration to lymphoid organs and result in the development of a tertiary lymphatic tissue within the bowel wall maintaining the autoimmune inflammation in Crohn's disease."],["dc.identifier.doi","10.1136/gut.2004.063008"],["dc.identifier.isi","000234553500019"],["dc.identifier.pmid","16118351"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42291"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","B M J Publishing Group"],["dc.relation.issn","0017-5749"],["dc.title","Increased number of mature dendritic cells in Crohn's disease: evidence for a chemokine mediated retention mechanism"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
